INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek MX2 / MXR2
series
media converter. Please take a
few minutes to read these installation instructions in order to obtain the maximum performance from
this product.
FUNCTIONAL DESCRIPTION
The
MX2 / MXR2 s
eries
combines
a single
fiber
Ethernet
port with two copper Ethernet ports. The

units
al
low transmission
speeds of 10 Mb/s or 100 Mb/s on each of the copper
port
s
.
The fiber port transmission speed is set at
100 Mb/s. The MX2 / MXR2 series converts the electronic Ethernet input into an optical output using a
1300 nm wavelength source. The MX2 / MXR2 series also converts an optical Ethernet input signal
returning on a separate fiber into an electronic Ethernet output using a
130
0 nm wavelength detector.
The

units operate on 9 um
single
mode fiber with a maximum distance of 20 Km. Refer to the data sheets for detailed performance
specifications.
The
MX2 / MXR2
series
is configured to auto negotiate the copper ports to
either
10Base-T or
100Base
-TX Ethernet data at full or half duplex.
The auto negotiate feature also selects the proper MDI
or MDIX interface. The MX2 / MXR2 series fiber port is set to 100Base-FX and is compatible with
IEEE802.3 100Base
-
FX standard products.
T
he
availability of both a copper and a fiber port allows the
MX2 / MXR2 series product
to
be used
as
a
straight through Ethernet media converter, changing an electronic data signal to a fiber optic data
signal.
This unit is contained in a compact and rugged aluminum housing with internal dc voltage regulation.
The detachable terminal block, RJ45 Ethernet data
connector
, and LED indicators provide for easy
installation and monitoring of data and dc power. The
MX2
s
eries
is designed for mounting as a
modula
r stand alone unit.
The MXR2
s
eries is designed for rack mounting
in the MXRC
-
1 subrack
.
INSTALLATION
THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND SHOULD
CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70 AND LOCAL CODES.
Mount
MX2 series units
to
a secure surface using #8 (3mm) hardware in four places. See the
drawing
on the next page for mounting dimensions. Be sure to allow sufficient room for the required minimum
bend radius of the fiber cable used.
MXR2 series units slide into any open slot in the MXRC-1 subrack. Use a small screwdriver to screw
the top and bottom fasteners into place.
